May 23, 1963: Dave Dingman, with Germe Dorje Sherpa, made his second rescue of the expedition, helping Tom Hornbein, Willi Unsoeld, Barry Bishop, and Lute Jerstad down from their bivouac at 28,000 feet on #Everest. Amazing history. Sharing it all with High And Hallowed tomorrow night at @mountainfilm. #highandhallowed #everest1963

50 years ago today, Tom Hornbein and Willi Unsoeld were making their way up the Hornbein Couloir to Camp 5 West on #Everest for their summit bid on the West Ridge, supported by Barry Corbet, Al Auten, and some amazing Sherpa. Amazing ascent. #climbinghistoryandheroes
